STAVE-MACHINE.

Specification of Letters Patent No. 20,737, dated .Tune 29,'18158.

To all whom 'it may concern:

Be it known that I, WILLIAM M. SLoANn, of BuEalo, in the county of Erie,in the State of New York, have invented new and useful Improvements inSta've-Dressing Machines; and I do hereby declare that the following isa full and exact description thereof, reference being had to theaccompanying drawings, and to the letters of reference marked thereon,making a part of this specification, in which- Figure I, is a sideelevation. Fig. II, rs a plan. Fig. III, is an elevation of thevertically moving frame and the cutters supported therein, and the cams,and the c onnection thereof to the frame and gearing for driving thesame; Fig. IV, end elevation of the feed and pressure rollers andgearing for driving the same. Fig. V, represents the arrangement of thatportion of the gearing which connects with the main wheel to drive thefeed and pressure rollers and one of the cams. Fig. VI, is a plan of thecam and diagram of the formula for obtaining the form thereof.

The nature of my invention relates, lst, to operating two rotaryadjustable cutters in a vertically moving frame, as hereinafter morefully set forth; 2d, in the arrangement and combination of the saidcutters in relation to a revolving bed, feed-rollers and former, asherein set forth. 3d, in the construction of a cam of peculiar form forthe purpose of communicating the required movement to the said framesupporting the said cutters.

A (Fig. I) rotating bed or main wheel upon which the stave is fed to thecutters and formed; o, cog rim attached to said wheel; c, main frame, orbed which supports the machine; c, .0, secondary frame which supportsthe gearing and cutters;

(Z (Z, gear wheels which drive the feed and pressure rollers. Upon theopposite end of the shaft is a smaller wheel, (Z2, (Fig. IV) whichmeshes in with cog rim b.

e, e, e, e, series of gear wheels on same shafts with feed and pressurerollers; F, vertically moving frame, which supports the two revolvingcutters; y

G, driving pulley on said cutter shaft. The arrangement of these pulleysand shafts is more fully shown in Fig. III.

I-I, upright posts, which guide the frame z' z', set screws, which withthe rubber springs J J, regulate the pressure of the rollers; K, cam,which gives the proper vertical movement to the frame F, and cutters, inorder to dress the edge of the stave upon the required bevel and bilge;L, guide or former under which the stave passes to hold it to the bed.

M, nib, projecting from the face of the rotating bed, against which thestave is Aplaced to be fed to the cutters; it also acts as a gage tobring the stave to the action of the cutters at the proper point.

N, table, on which the stave is placed in order to be fed to thecutters; M n, parallel gage;

O (Fig. II), main driving pulley. A small pinion O2, (Fig. IV,) is uponthe opposite end of this pulley shaft and meshes into the cog rim (52,)on rotating bed.

P, horizontal revolving cutter which dresses the outside of the stave;Q, pulley which drives the same; R R, cutters, supported in thevertically moving frame, and which dress t-he edges Aof the stave; G,Gr, pulleys which drive the same; S S, feed and pressure rollers;

25, t; feed rollers on same shaft with middle wheel c. These rollers areconvex (the reverse of the feed and pressure rollers above them, whichare concave) and in connection with the face of the rotating bed, givethe inside transverse curve to the stave;

u, a, (Fig. III) arms, connecting the cams K to the frame F. These armsare connected to a circular band which surrounds the cam, o-r instead ofthe band the arms may set upon the cam, and the frame weighted so thatthe frame will follow the cam.

The cutter shafts are made adjustable in the circular slots r2 so thatthe cutters may be set upon any given level, and adjusted to any widthof stave and any size barrel.

o fu, set'screws, which hold the cams to shaft W and W1.

X X, pinions on same shafts with cams. These mesh in with cog rim b andb2. The gearing is so arranged as to give the cam one revolution whilethe rotating bed passes the distance between the nibs M, or the lengthof the stave.

Z, (Fig. IV,) support and journal bearing for shaft of driving pulley;Z2, support and journal bearing for shaft of pinions Z and d2; (Z2,pinion, which meshes in with cog rim b and drives the feed gearing c, c,c, c.

Letters of like name and kind refer to like parts in each of thefigures,

A peculiar form of cam, in connection with the revolving motion of thecutters, is requisite in order to give the required form oi stave tomake a barrel of any required lcurve or bilge. Hence I have adopted the'following formula to be observed in the conof equal parts (l, 2, 3,&c.) as the chord is divided, and draw radii (l, 2, 3, &c.) through eachof these points corresponding to the perpendiculars of the chord. 6th,on each of these radii, commencing with No. l lay oil distances equal tothe height of the perpendicular of the corresponding number on thechord. 7th, when all these points are obtained draw a line through them.This line (W H) will determine the form of the cam.

Operation: The stave which is to be dressed is laid upon the table N,and against the gage As the bed revolves the stave is moved quicklyagainst the gage M until taken by the feed and pressure rollers by-which it is carried along under the former L, to the cutters. Thecutters R It, are at their highest posit-ion when they commence to cutthe stave, and gradually descend until the revolving bed has carried thestave one-half its length, or to the center of its bilge at which pointthe cutters commence and continue their upward movement until the otherhalf of the stave4 is jointed. The horizontal cutter P at the same timedresses the outside of the stave upon its transverse curve. The camcommunicates the required vertical movement to the frame l?, and cuttersR, R, and each stave is dressed upon its required bevel, bilge, andcurves with mathematical correctness.

I claim-f 1. Operating the two rotary cutters (It, R,) in a verticallymoving frame (IQ) substantially as herein set forth.

2. I claim the arrangement oi the cutters R, R, and P, relatively to therevolving bed A, former L, and feed-rollers for the purposes andsubstantially as herein set forth.

3. I claim the cam (K) when constructed according to the formula, andused for the purpose as herein set forth.
